PROFILE
A. Sophie Blee-goldman
Worked on the slatedb/slatedb repository to optimize SSTable index block size by introducing a lower bound key approach. This involved refactoring the index block creation process and implementing a compute_index_key utility to derive the lower bound from adjacent block keys. The EncodedSsTableBuilder in src/sst.rs was updated to utilize this new computation, changing how first_key and current_block_max_key are managed. By reducing index block size, the update decreased I/O and improved read performance for large datasets. The work demonstrated proficiency in Rust and systems programming, with a focus on data structures and performance optimization in key-value store architectures.

Mar 1, 2025In 2025-03, delivered a key optimization for SSTable indexing in the slatedb/slatedb repository by adopting a lower bound key to shrink index block sizes. The change refactors index block creation and introduces a compute_index_key utility to derive the lower bound from the previous block's last key and the current block's first key. EncodedSsTableBuilder in src/sst.rs was updated to use the new key computation, altering how first_key is stored and how current_block_max_key is managed. Commit: 1ef43dde5020d45a9b08247b1d5f1a56a239eaee (Reduce size of index blocks using lower bound index key, #516).
